The 'time capsule' feature will allow people to leave a confidential message on the 2021 census.
The government has announced that the next census will take place on Sunday 18 April in 2021.
Every other EU member state will do the same at some point in the year.
The census will have a total of eight new features, as well as all of the 25 original questions that are normally on the census, although a number of them have been updated.
According to
RTÉ, the new questions will be focused on renewable energy sources, smoking, volunteering, childcare, commuting home from work, school or college, internet access and devices, smoke alarms and working from home.
As well as that, there will be a new space made available for you to write a confidential piece of information that will be stored securely for 100 years.
Speaking on RTÉ's News at One, Senior Statistician at the CSO Cormac Halpin said:
"We thought it would be a good idea for people to get the opportunity to add some handwritten content themselves to the back of the Census form that will be stored for 100 years in a confidential, secure warehouse.
"We think it gives people the opportunity to add something to their Census form that they might not have the opportunity to do elsewhere."
Sounds fun. So if you have plans on Sunday 18 April in 2021, cancel them now.
